Introduction

This document contains the release notes for the interactive C++ interpreter Cling, release 0.6. Cling is built on top of Clang and LLVM compiler infrastructure. Here we describe the status of Cling in some detail, including major improvements from the previous release and new feature work.

Note that if you are reading this file from a git checkout or the main Cling web page, this document applies to the next release, not the current one.

What's New in Cling 0.6?

Some of the major new features and improvements to Cling are listed here. Generic improvements to Cling as a whole or to its underlying infrastructure are described first.

External Dependencies

  • Upgrade to LLVM r302975.

Major New Features

  • Integrate the automatic differentiation library clad as a cling plugin.
  • Implement basic plugin support -- cling can load shared libraries which can specialize its behavior. It relies on the clang plugin infrastructure.
  • Emulate thread local storage (TLS) on the platforms where the JIT does not support natively.
  • Clang and LLVM optimizations of interpreted code, defaults again to -O0

Misc

  • Optimize cling pointer validity checks.
  • Speed up the LookupHelper facilities by introducing a parsing cache.
  • Implement Control+C and Control+D support.
  • Support printing lambda-dependent types.
  • Various minor improvements for C++ modules support:
    • Adjust module cache path;
    • Build the cling runtime into a separate module;
    • Support virtual filesystem overlay files;
  • Use COFF object file format on Windows -- fixes symbol lookups.

Experimental Features

  • Start working on CUDA support

Jupyter

  • Provide better diagnostics if cling was not found;
  • Find back the kernel if brew install was used;
